The utility model designs the semi-automatic transmission for aiming at avoiding the phenomena of easy flameout, easy self running and the like caused by the need of semi-clutch when starting the automobile with a stick-shift, and solving the problems of unsmoothness and the like caused by power failure during gear shifting at a low speed. The utility model has the technical structure that an engine (1) and a stick-shift (8) are connected through a hydraulic converter (3) to realize the semi-automatic operation of automatic gear shifting at the low speed and manual gear shifting at the medium and high speed. The utility model has two forms: one form is that a pump wheel of the hydraulic converter (3) is connected with an engine flywheel (2), a turbine of the hydraulic converter (3) is connected with the input end of a main clutch (4), the main clutch (4) is arranged behind the hydraulic converter (3), and the output end of the main clutch (4) is connected with a transmission input shaft (5); and the other form is that the main clutch (4) is connected with the engine flywheel (2); the hydraulic converter (3) is arranged behind the main clutch (4), the pump wheel of the hydraulic converter (3) is connected with the main clutch (4), and the turbine is connected with the transmission input shaft (5).
Description
Technical field
The utility model relates to a kind of automobile component---Automotive transmission.
Background technology
Up to the present, Automotive transmission is two classes basically, and a class is mechanical hand-operated transmission, and a class is an automatic transmission with hydraulic torque converter.
The advantage of hand-operated transmission is that cost is low, and is more fuel-efficient, easy to maintenance.Flame-out, slide car phenomenon with half-clutch, easily takes place during starting in dynamic interruption when shortcoming is gearshift; Starting back low speed needs first open the throttle wide when adding retaining, stops then refueling, and steps on power-transfer clutch and adds retaining, adds retaining back loosen the clutch and refuels, and the low inertia of speed of a motor vehicle this moment is little, and positive negative acceleration is big, has a strong impact on ride comfort (the pause and transition in rhythm or melody sense is obvious); Driver's labour intensity is big, and the occupant feels under the weather.
The advantage of automatic transmission with hydraulic torque converter is that to drive labour intensity little, and ride comfort is good, and uphill starting can not slip car or flame-out.Shortcoming is the cost height, technical sophistication, and China's autonomous production ability does not still have at present, the basic need import, fuelling rate is higher, maintenance difficult etc.
What the many technical risks of number of operations were big in actual the driving is bottom gear, if the uneven compliance of shifting gears when having solved vehicle starting and low speed, and easily slip car or flame-out phenomenon during uphill starting and just solved the basic problem of vehicle drive.Very much not ride comfort is not obvious owing to inertia in gearshift during high speed, and the energy high speed when travelling its number of operations do not understand many yet.
Summary of the invention
Need be during for solution hand-operated transmission vehicle starting with half-clutch, phenomenons such as easy generation is flame-out, slide car, and when low speed is shifted gears, cause problems such as irregularity because of dynamic interruption.The present invention adopts between driving engine and hand-operated transmission with turbine transformer bonded assembly technical scheme.The semi-automatic operation of hand gear when automatic speed changing, high speed when realizing starting and low speed.Can solve the starting irregularity like this, slip car or problem such as flame-out during uphill starting, make manufacturing cost lower again, more fuel-efficient, easy to maintenance, and have driving enjoyment, the present level of manufacturing technology adaptation China.

The specific embodiment
The utility model has two kinds of technical schemes: a kind of scheme is (referring to accompanying drawing 1 and an accompanying drawing 3), the pump impeller of turbine transformer (3) is linked to each other with engine flywheel (2), turbine links to each other with master clutch (4) input end, master clutch (4) at turbine transformer (3) afterwards, the mouth of master clutch (4) links to each other with input shaft (5) in the hand-operated transmission (8), and transmission output shaft (6) is gone up to install by the opening of control of reversing gear and closed single clutch (7).Another kind of scheme is (referring to accompanying drawing 2 and an accompanying drawing 4), master clutch (4) is linked to each other with engine flywheel (2), turbine transformer (3) is contained in master clutch (4) afterwards, its pump impeller links to each other with master clutch (4) mouth, turbine links to each other with input shaft (5), and transmission output shaft (6) is gone up to install by the opening of control of reversing gear and closed single clutch (7).
In order to increase work efficiency, save fuel oil, turbine transformer adopts the technical pattern of with lock ending (lock was one when turbine and pump impeller reached certain rotating speed), and the technology of ending with lock comprises electromagnetic technique, change hydraulic technology and centnifugal force technology etc.
In order to utilize Jake brake when the lower long slope abrupt slope,, in case of necessity turbine and pump impeller lock are one, but make the power back transfer for turbine transformer is established a manual lockable mechanism.
Working process of the present utility model is: low speed (30～40Km/h is following) retaining is directly linked to each other with 1 retaining gear pair by turbine transformer and realizes automatically, the torque ratio of turbine transformer is between 2～3, the speed ratio design of first gear is about 2, the two back bending moment multiple that links to each other can reach 4～6, is fit to the starting requirement.Hang up 1 retaining before the vehicle starting, loosen the clutch, slam brake pedal, the same with automatic transmission with hydraulic torque converter, the releasing of brake pedal refuels during startup, work near the range of speed of driving engine from the idling to the torque peak, the rotating speed of tor-con turbine and pump impeller is approaching to rotating speed by the maximum speed difference, and automobile is from the static 30～40Km/h that accelerates to, in the time of after this need continuing to raise speed by the hand-operated transmission method of operation, lift throttle and step on power-transfer clutch and add retaining, loose then clutch is refueled.Subtract retaining by the hand-operated transmission method of operation during deceleration, can utilize neutral to slide in the time of need sliding with saving fuel.In order to prevent that ramp starting from slipping car, the controlled free-wheel clutch by the control of reversing gear is installed on output shaft, not hanging can only advance when reversing gear can not retreat, and hangs up the back one-way clutch function cancellation of reversing gear when needing reversing.
The utility model is the normally closed state that closes when bottom gear owing to master clutch, thereby looks many service life than the power-transfer clutch of pure hand-operated transmission.
